Meteorology is the study of:
The Atmosphere
Weather describes the conditions averaged over a region or over a period, whereas climate describes
the condition of the atmosphere at a particular time and place.
False
In ____ near Earth's surface today, nitrogen occupies 78 percent and oxygen nearly 21 percent.
The volume of air
Atmospheric concentration of helium has increased from below 300 ppm historically to over 400 ppm
presently.
False
In which atmospheric layer is most of the ionosphere found?
Thermosphere
The region where atoms and molecules shoot off into space is sometimes referred to as the
exosphere, which represents the upper limit of our atmosphere.
True
Precipitation is
Any form of water that falls from clouds and reaches the ground.
Meteorology is the study of the atmosphere and its phenomena. The term itself goes back to the
Greek philosopher, Aristotle, who wrote a book on natural philosophy entitled Meteorologica.
True
Most human-made impurities found in the atmosphere present a health and environmental hazard.
These are called ____.
Pollutants
Which of the following is considered a variable gas in Earth's atmosphere?
Water Vapor
Carbon dioxide is a naturally occurring component of the atmosphere.
True
The atmospheric concentration of CO2 has risen by about ____ since 1958, when measurements
began at Mauna Loa Observatory in Hawaii.
about 30%
,Of the four most abundant gases in our atmosphere, carbon dioxide shows the greatest variation at
Earth's surface.
False
The two most abundant greenhouse gases in Earth's atmosphere are carbon dioxide and water vapor.
True
Water vapor can best be described as a ____.
Gas
A geostationary satellite takes pictures of ____.
One area on earth as it moves at the same rate as earth's spin
Our understanding of the atmosphere and how it produces weather is built on the knowledge
acquired and applied through the scientific method.
True
Almost all of Earth's weather occurs in the ____.
Troposphere
The region where atoms and molecules shoot off into space is sometimes referred to as the
exosphere, which represents the upper limit of our atmosphere.
True
A constant outpouring of gases from the hot interior—known as ____—provided a rich supply of
water vapor, which formed into clouds.
Outgassing
The ozone hole is an actual hole in the atmosphere, a region of complete vacuum.
False
The word "weather" is defined as ____.
The condition of the atmosphere at a particular time and place.
In a warm front, what is being replaced?

Which process, over millions of years, provided a rich supply of water vapor into the atmosphere that
formed into clouds?
outgassing
Which process acts to remove carbon dioxide from the atmosphere?
Photosynthesis
The majority of ____ on our planet is believed to have come from its hot interior through outgassing,
although some of Earth's water may have come from collisions with meteors and comets.
Water
In the isothermal zone of the atmosphere, the air temperature, on an average, remains constant with
height.
